SPECIFICATION forming part of Letters Patent No. 450,042, dated April '7, 1891.

Application filed J u ly 18, 1889. Serial No. 817,868. (No model.) Patented in Germany April 30, 1889, No. 50,114, and in England May 22, 1889.110. 8,538.

To 61% whom it may concern.-

Be itknown that I, RICHARD SOHULZ, inanufacturer, a subject of the King of Prussia, residingat 61 Sebastianstrasse, Berlin,Prussia, German Empire, have invented certain new and useful Improvements in Brushes, (for "which 1 have obtained Letters Patent in the following countries: Germany, April 30,1889, No. 50,114, and in Great Britain May 22, 1889, No. 8,533,) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification, and in which- Figures 1 and l are longitudinal vertical sections of my improved folding brush, showing the same, respectively, ready for use and folded. Figs. 2 and 3 are sections on lines 1 1 and 2 2 of Fig. at. Fig. 5 is a side and end elevation of one of the pivoted brush-bars. Figs. 6 to 10, inclusive, are detail views of a portion of the brush case, illustrating the means for rocking the brush-bars, Figs. 11 to 1%, inclusive, showing a modification in the means for actuating the brush-bars, Figs. 11 and 14 being sections similar to those shown in Figs. 1 and 4, respectively; and Figs. 12

and 13 are sections taken on lines 3 3 and 4. 4 of Fig. 11. Figs. 15 to 21 show another modification in the construction of the brush, Figs- 15 and 20 being sections similar to those shown in Figs. 1 and 4.. Figs. 16 and 18 are sections taken on lines 5 5 and 6 6, respectively, of

Figs. 15 and 17, Fig. 17 being a part elevationand part section of the brush. Fig. 19

is a horizontal transverse section thereof, and

23, 2b, and 31 are sections taken on lines 7 7, '8 8, and 9 9 of Figs. 22, 25, and 30, respectively; and Figs. 29 and 33 are detail views.

Folding brushes as heretofore constructed for use, generally as pocket-brushes, present inconveniences, in that they are not handy, in that the brush-case is usually very large relatively to the brush itself, and in that the brush is subjected to rapid wear, the folding of the brush-bundles being effected by the action of the case-cover thereon.

The object of this invention is to obviate these inconveniences; and it consists in structural features and combinations of parts, substantially as hereinafter described, and as set forth in the claims.

In my improved brush the bundles of bristles and their supports are so connected with such supports within the brush-case may be greatly varied, as will hereinafter appear.

Referring more particularly to Figs. 1 to 10, inclusive, b indicates the brush-case, and a the bars or shafts to which the bundles of bristles are secured,said bars or shafts being formed of sheet metal bent to the shape shown more clearly in Fig. 5, the bundles of bristles being secured to the shaft in any well-known or suitable manner. The shafts C0 are pivoted on pins 1), projecting from the side walls b of the casing 12 and said pivots or journals may be soldered or otherwise secured to said side walls, or they may be formed by stamping,

.the casing being preferably constructed of sheet metal. These journals. fit into the cylindrical or tubular bent portion of the shaft a, as shown in Fig. 2; but it is obvious that the journals may be secured to the shaft itself, as shown at 12 Fig. 5, and bearings provided in the side walls of the casing for such journals. Each of the shaft-so. is further provided at one end with a journal or pin 0, that extends into a slot 0 of an actuating bar or rod (1. This bar has an endwise motion in a chamber formed between one of the side walls of the casing and an intermediate wall Z), secured to said side wall or formed integral therewith by bending a portion of said side wall over and inwardly, as shown in Fig. 2, said inner wall or partition serving not only to properly guide the actuating-bar, but for locking the brush-shafts a into position, said wall or partition having a series of recesses b the rear wall of which is vertical, while the forward wall is curvilinear. The horizontal wall of the recesses Z2 is at such an elevation from the bottom of the brush-casing as to been a line with the like walls of the vertical slots 0' in the actuatingbar d, as shown in Fig. 4.

It will be readily seen that when the brushes are folded within the case, as in Fig. 4, the pin 0 of the shafts a lies at the upper end of the slot 0' and within the recess Z9 but when said bar d is caused to move in the direction of the arrow 1,Fig. 1, the pin c rides along the curvilinear front wall 19 of the recess, moving downwardly until it has reached the under side of the partition or intermediate wall 1), thereby tilting the brush-shafts a, into the position shown in Fig. 1, with the bundles of bristles in a vertical direction for use, while if said bar at is caused to move in the direction of arrow 2, Fig. 4, the shafts a will be tilted so as to bring the bundles of bristles into atfolded position, as shown in Fig. 4:.

In order to elevate or lower the bundles of bristles without applying power directly thereto, thereby avoiding the wear resulting from such direct application of power, I- operate the actuating-bar through the medium of the lid or coverf. This lid or coverf is hinged, as shown at f, to a semi-cylindrical end piece 9, that closes one end of thebrushcase and is pivotally connected with the side walls thereof. The outer end of the actuating-bar d is also semi-cylindrical, and is providedwithan irregular slot d, into which projects a stud 9 secured to the semi-cylindrical end piece 9, said slot having the curved portion 8, in the end of which the stud g lies when the brush-case is closed and the brushshafts to are tilted toward the left, as shown in Fig. 6.

If the lidf is turned over after being unlocked from the case, the lid having the locking-lipf that engages with the edge 12 of the semi-cylindrical outer end of the brush-case b the semi-cylindrical end piece g will be revolved on its pivots g, and the stud or pin g thereof will travel along the curvilinear face 8 of the slot d (which face is a segment of a circle having the pivots g for the center) until said pin reaches the abutment or verti-' has completely cleared the brush-case and is out of reach of the brushes, the; pin moving from the shoulder 5 to the locking-shoulder 6, Fig. 8, the end piece 9 having made onehalf of a revolution on or with its pivots g, and its position will have been reversed, as shown in Figs. 1 and 8, the coverf' being then in the position shown in said Fig. 1, so that the brush-case can be used with the greatest ease. A reverse movement of the coverf or in the direction of arrow 9, Fig. 1, will cause said cover to impinge upon the projecting slotted end of the actuating-bar as soon as said cover reaches the position indicated by dotted lines in Fig. 1, during which movement of the cover f-the stud g will have moved from the locking-shoulder 6 to the shoulder 7. and end piece 9 will move the actuatingbar inward, thereby tilting the brush-bars toward the left to fold the brushes within the case, when the cover will be about in a vertical position above the case, and the stud will have passed from the shoulder 7 to the curved face 8, and when said cover fully closes the case b the said stud 9 will have returned to of perforated ears b projecting from tliebottom thereof, the shafts a being actuated by a crank-arm g pivoted eccentrically at g to the semi-cylindrical end piece g.-

In Figs. 15 to 21 I have shown the brushshafts a pivotally connected with the actuating-bar d at one end and with the casing through the medium of perforated strips or flanges Z, projecting from the bottom thereof; or said flanges may be formed by slitting the sheet metal andbending a portion thereof i-n'-. wardly, as shown'in Fig. 16. The actuatingbard has at its left end a stud or pin d that projects into a slot Z in the side wall of the case Z. (See Figs. 18 to 21.) Instead of a cover such asheretofore described, the brushcase is inclosed in an outer casingh, that has a slotted locking-piece h secured to its side wall by means of a screw 72 the slot in said locking-piece lying in the path of the pin or stud d so that when the brush-case Z, with the bundles of brushes turned down, is withdrawn from the inclosing-casing 7i and the stud or pin d reachesthe end of the slot in the locking-piece 77, said stud will be held against further motion. If now the brushcase Z is drawn out to its full limit or in the direction of arrow 10, Fig. 17, the actuatingbar cl will be drawn in a reverse direction,

A further rotation of the cover said brush-casing.

(shown by arrowll, Fig. 15,) imparting thereby a partial rotation to the brush-shafts and brushes, bringing the latter in a vertical position for use. To the inner end of the brushcase Z is secured a pin 70, that carries a coiled spring and a flanged locking-button 70' which projects through a slot in casing Z and into a longitudinal slot 72, in the outer casing. The tendency of the spring is to force the button outward;bnt the latter is held against the action of the spring by the edges of the slot 7L3, which fit into an annular groove 1, Figs. and 16, formed in said button. At its outer end the slot 71 is enlarged, so that when the brush-case is drawn out of its inclosing casing and the button reaches the enlarged end of slot 72. it will be forced outwardly by its spring, so that the button will lie in the enlarged portion of said slot h thus locking the brush-case to the inclosing casing 72. and preventing the further outward motion of the If the brush is to be pushed back into its inclosing casing, the button k is pushed in until the edges of the narrower portion of the slot will enter the groove 2' in the button, when the brush-case can be moved inwardly. During this inward motion of the casing the inclined face 12, Fig. 17, of the slot in the locking-piece It will cause the actuating-bar to move from left to right, thus tilting the brushes, as shown in Fig. 20. After the brush-case has been fully pushed into the inclosing casing, the hinged end lid 71 is turned up and locked to the inclosing casing, as shownin Fig. 20, by springing the same into the edge groove thereof.

Figs. 22 to 24 show but a slight modification in the construction of the brush described in reference to Figs. 15 to 21. The lockingpiece It is here dispensed with, a slot 77, in the side wall of the inclosing casing Z being substituted therefor, and the brush-shafts are journaled directly to the side walls of the brush-casing Z.

In the modified construction shown in Figs. 25 to the brush-shafts are journaled in the turned-up edge of a casingm, that has an endwise motion in the brush-case Z. When the brush-case Z is drawn out of its inclosing casing 71, and before said brush-case is fully drawn out, one of the arms of a lever 12, pivoted at 0 to the brush-case, enters a recess h in one of the side walls of the inclosing casing h, thereby causing said lever to revolve on its pivot 0. The other arm of the lever n is forked and straddles the rear wall of casing m, to which is imparted an accelerated forward motion relatively to the brush-case Zas soon as the lever-arm strikes the front wall of said recess h. Simultaneously therewith the pin d on the actuating-bar cZ reaches the end of the slot Z in the side wall of the brush-case Z, whereby the motion of said bar, with the case, is arrested and the brushshafts a tilted to erect the brushes for use, a hook Z Figs. and 27,1ocking the inclosing and brush cases together. On depressingthe hook and pushing the brush-easel into the inclosing casingh the lever-arm strikes the inclined surface 15, so that the casing on will receive a motion in a direction the reverse of that indicated by arrow 13, Fig. 28, whereby the actuating-bar d is again actuated to turn the brushes down, as shown in Fig. 27, the pin 0Z moving down into theinclined portion of slot Z Fig. 29. i

In the modification shown in Figs. to 33' the actuating-bar d is controlled by the sliding lid 19 of the brush-case, which latter is provided with longitudinal grooves s and 0', respectively, into which the edges of the lid 19 fit. By sliding the lid p along the grooves s the brush-case can be closed, as shown in Fig. 32, the brushes being at the same time turned down. On the'contrary, by sliding the lid along the grooves 0, Figs. 30 and 31, the end of said lid strikes the proj ections d on the brush-actuating bar (1 and displaces the same, whereby the brush-shafts are tilted and the brushes erected for use.

The brush-shafts are in this construction also provided with journals 12 that have their bearings in the side walls of the brush-case Z.

Other modifications in the construction and arrangement of the co-operating parts will readily suggest themselves to the skilled mechanic. One of the essential features of the invention consists, however, in that the brushbundles are not directly acted upon to turn the same down or out of use, as has been the case heretofore, and whereby such brushes are injured and rapidly destroyed.

Having now described my invention, what I claim, and I desire to secure by Letters Patent, is-

1. In a folding brush, abrush-case, a series of brush-shafts journaled therein, and a rockbar connected with the brush-shafts for rocking the same in their bearings, in combination with a cover for the case and a connection between the cover and rock-bar for positively operating said bar on opening and closing the brush-case, substantially as and for the purpose set forth.

2. In a folding brush, a brush-case, a series of brush-shafts journaled therein, and a rockbar connected with the brush-shafts for rocking the same, in combination with a cover for the case, adapted to positively operate said bar, for the purpose set forth.
